Qualcomm has a host of new technologies in store, including an ultrasonic fingerprint scanner, cognitive machine learning for your smartphone and tablet, and, of course, a new processor: the Snapdragon 820.

Qualcomm today at MWC 2015 announced their newest device security measure: an ultrasonic fingerprint scanner. Dubbed Qualcomm Snapdragon Sense ID 3D Fingerprint Technology, the tech uses ultrasonic waves to penetrate through the outer layers of your finger to build a three-dimensional map of your fingerprint that's much harder to duplicate than a mere capacitive scanner as you'd find on the Samsung Galaxy S6 or iPhone 6. Additionally, Qualcomm also announced their new "machine learning" platform Zeroth, which aims to go for a device that learns and adapts to how you use it.
